摘　　要：膜筏微区(membrane microdomains)是细胞质膜上富含固醇类和鞘脂类的高度动态的微结构域。膜筏微区及其动力学特性在植物的先天免疫反应中具有十分重要的作用。本文简要介绍了膜筏微区的概念及其功能,并着重总结了膜筏微区蛋白参与病原菌防御反应的研究进展,为阐明病原菌与宿主细胞的相互作用机制和病原菌侵染的防治提供了新思路。Membrane rafts are dynamic nano-scale domains enriched in sterols as well as sphingolipids. Recent studies suggest that plant membrane microdomains and their dynamics may play vital roles in the plant immune response. This review mainly focuses on the characteristics and the proposed biological roles of membrane microdomains,with special emphasis on the recent progress of membrane microdomain-associated proteins involved in the immune signaling in plant cells,which provides valuable information for further study on the mechanism of interaction between pathogens and host cells and infection prevention in plants.
